Slated to hit shelves in late May 2017, Mars' new M&M's feature a caramel center covered in chocolate and coated with the brand's colorful candy shells.

"Chocolate and caramel is such a popular flavor combination, especially with the fans of M&M'S," Tanya Berman, brand director of M&M'S brand, said in a statement. "In our research, our fans were enthusiastic at the possibility of a caramel variant."

Caramel is just the latest flavor of M&M's to be rolled out by Mars, although it is unclear if it will be a limited-time offer or a new staple product. Previous temporary additions include coffeenut, coconut, pumpkin spice and carrot cake.
